 subscriptions received from that Contract- 

 ing Body.

 ceived by the Central Bureau before the 

 date fixed as above provided, the copies of 

 the catalogue supplied in that year to any 

 Contracting Body shall be a specified num- 

 ber of complete sets, i. e., shall contain an 

 equal number of all the volumes allotted to 

 the different sciences. 



If any Contracting Body requires a larger 

 number of volumes than are covered by its 

 subscriptions, such volumes may be sup-

 the Central Bureau.

 right to have the schedules and alphabetical 

 indices prefixed to the volumes allotted to 

 it in return for its subscription printed in 

 English, French, German or Italian, as it 

 may prefer. 



If no request is made to the contrary, the 

 language of the schedules and indices shall 

 be English. ( 96.29.)

 Catalogue printed in each year shall be in

 plied to the Contracting Bodies shall be 

 such as to cover the cost of production of 

 such excess volumes, which, if wanted 

 thereafter by any of the contracting bodies, 

 shall be supplied to them at specified 

 prices. 



42. If the sale of the Catalogue or of the 

 additional volumes result, in any year, in a 

 pi'ofit, this profit shall be allowed to accum- 

 ulate, and may be used by the International 

 Council to cover a deficit in any other year; 

 provided always that neither the scope of 

 the Catalogue shall be increased, nor the 

 total number of 200,000 entries exceeded. 



without the direct permission of the Inter- 

 national Convention. 



If the Catalogue shows a profit after 

 several years' working, the International 

 Convention shall decide how the profit is 

 to be applied, whether to increase the scope 

 or the bulk of the Book Catalogue, or to 

 the issue of a Card Catalogue. 



43. The publication of the Catalogue 

 shall not be undertaken unless the shares 

 taken up cover the estimated cost of the 

 catalogue. 



44. The publication, if undertaken, shall 

 be an experiment for five years. All the 

 Contracting Bodies shall agree to continue 

 their subscriptions for five years, and the 

 International Council shall not make con- 

 tracts extending beyond that period.
